"The key differences between the Sapphire Radeon HD
4870 Toxic and the normal Sapphire Radeon HD 4870 or any of the
other HD 4870 graphics cards from other AIBs is the factory
overclock and the graphics card cooler. The Sapphire Radeon HD 4870
Toxic arrives with a 780MHz core clock and 1000MHz memory clock.
This is in comparison to the reference specification for the
RV770XT (Radeon HD 4870) that calls for a 750MHz core clock and
900MHz GDDR5 memory clock."
